What would your survival get away bike be if we had no gas nor electricity?

I had an idea of solar power, some kind of twist fan? Steam engine? Anything new? Be creative and think! Think of something that u could make that be the best approach for woods, water, roads and even yards.

A steam engine still needs fuel or electricity to make the steam. Solar power requires a large solar panel array to convert sunlight to electricity. If you have no reliable alternate source of fuel, your best bet is still human power.
